9 Claims.

This invention relates to cleats such as are attached to the sole ofshoes worn by athletes and has for its primary object to provide animproved cleat anchoring means, as Well as a cleat of improvedconstruction. The subject matter herein disclosed relates to the sameclass as the subject matter of my applications Serial No. 270,- 613,filed April 28, 1939, and Serial No. 280,648, filed June 22, 1939, towhich cross reference is hereby made.

The main object of this invention is to provide cleat anchoring means inwhich the cleat retaining member is placed in operative or inoperativeposition from the inside of the shoe. In this respect the cleat isprovided with a stud which extends through the sole and having ascrewthreaded end upon which a nut is placed from the inside of the shoeto retain the stud in the sole. Such an arrangement has an importantadvantage in that, it enables replacement of cleats Whose metalanchoring studs have become broken, for the reason that the brokenportions remaining in the sole may be pushed into the shoe, leaving theholes from which they were forced in condition for reception of the studof a new cleat.

Another object is to provide anchoring means of the character abovementioned including a flexible sheet metal plate for distributingpressure over a comparatively large area of the sole, and means coactingwith the plate for preventing rotation of the cleat studs in order thatnuts may be readily screwed thereon.

Another object is to provide a cleat composed of rubber and fabric, thefabric being spirally wound around the longitudinal axis of the cleat insuch manner that the edges of the wound fabric constitutes the wearsurface at the outer end of the cleat. This construction provides thedesired resiliency and at the same time provides a high degree ofstrength and wear resisting properties.

Other objects and advantages will become more fully apparent asreference is had to the accompanying drawing wherein my invention isillustrated, and in which:

Fig. 1 is a bottom view of a shoe, illustrating cleats anchored to thesole thereof,

Figs. 2 and 3 are elevations of the metal sole and heel platesrespectively,

Fig. 4 is a section taken on the line 4-4 of Fig. 1,

Fig. 5 is a plan of the nut,

Fig. 6 is a section taken on the line 66 of Fig. 4 and pearance ofrubber, but the usual characteristics 10 of the rubber are changed. Thecleat may flex to a desired extent, will not compress under the weightof the wearer because the width of the fabric opposes compression, andwear resistant qualities are materially improved because the 1 5;

edge or edges of the ribbon or ribbons are exposed at the tip.

The anchoring means for the cleat comprises a metal stud 3, having ascrewthreaded end 4 and an enlarged head 5 on its other end. The 20 head5 is imbedded in the cleat l at the time the rubber is vulcanized, andthe stud 3 is of angular cross section, preferably hexagonal as may bestbe seen in Fig. 6.

A sleeve 6, of cross section similar to that of 25" the stud 3, and.having an end flange 1, is inserted in a suitable hole in the sole 8,and the flange l engages the outer surface of the hole. The sleeve 6also extends through a hexagonally shaped aperture 9 in a sheet metalplate It and has its 30".

inner end spun or otherwise bent over in the nature of a flange H, whichengages the top of the plate. The stud 3 is disposed within the sleeve 6with its inner or screwthreaded end 4 extending into an opening in aninsole I4 which 35,-

rests upon the plate It]. A nut I2, having an enlarged flange I3 isscrewed upon the stud 3 in such manner that the flange engages theinsole l4, and by compressing the sole 8, plate l0 and insole betweenitself and the sleeve flange 1,

tightly draws the cleat l against the flange 1.

From the foregoing it becomes apparent that the nut I2 is placed on thestud 3 from the inside of the shoe. It is held against rotation by thesleeve 6 and the walls of the apertures 9, and in order that the nuts [2may be rotated, they are provided with wrench receiving means such asthe radial slots l5, for example.

In the presence of extremely rough usage, as for example football gamesplayed upon frozen ground, the cleat anchoring studs 3 sometimes becomebroken. If this occurs, the broken stud and nut may be pushed inwardlythrough the sole assembly and removed from the inside of the shoe.Obviously, after removal of the stud the nut may be easily removedtherefrom, a new cleat stud placed in the sleeve from which the brokenstud was removed, and the same nut used toanchor the new cleat.

It is found that the presence of the nuts l2 do not cause discomfort tothe foot of the wearer for the reason that very heavy socks are usuallyworn with this type of shoe. In fact the socks ordinarilyworn are closeto one-quarter of an inch in thickness and, therefore, affordsufli'cient padding to make the presence of the nuts unnoticeable.

Although a specific embodiment of the invention has been illustrated anddescribed, it will be understood that various changes may be made Withinthe scope of the appended claims without departing from the spirit ofthe invention, and such changes are contemplated.

What is claimed is: Y

1. In combination, a shoe sole having an opening extending therethrough,a cleat having an endwise extending anchoring stud received in saidopening, metal means imbedded in said sole and holding said stud againstrotation, and a nut on the inner end of said stud and engaging the innersurface of said sole to retain said stud against removal from saidopening.

2. In combination, a shoe sole having an opening extending therethrough,a cleat having an endwise extending anchoring stud received in saidopening, metal means imbedded in said sole and holding said stud againstrotation, said metal means including a flexible sheet metal plate havingan area equal to a major portion of the area of said sole, and a nut onthe inner end of said stud and engaging the inner surface of said soleto retain said stud against removal from said openmg.

3. In combination, a shoe sole having an opening extending therethrough,a non-rotatable met'al liner for said opening of other than round crosssectional shape, a stud of other than round shape received in saidliner, a cleaton the outer end of said stud, and a nut on-the inner endof said stud engaging the inner surface of said sole to draw said cleatagainst the outer surface of the sole.

4. In combination, a shoe sole having anopening extending therethrough,a non-rotatable metal liner for said opening of other than round crosssectional shape, a stud of other than round shape received in saidliner, a cleat on the outer end of said stud, a nut on the inner end ofsaid stud engaging the inner surface-of said sole to draw said cleatagainst the outer surface of the sole, and a flexible sheet metal plateimbedded in the sole and coacting with said liner and stud intransmitting strains resulting from weight on said cleat over acomparatively large area of the sole.

5. In combination, outer and inner sole members having a flexible sheetmetal'plate interposed therebetween, said metal plate having an apertureof other than round shape and said sole members having openings inalignment'therewith, a cleat having a stud of other than round crosssectional shape, said stud extending through said openings, and a nut onthe inner end of said stud and engaging the inner surface of the innersole member to draw said cleat against the outer surface of the outersole member.
